Queclink GV300 is a compact system designed for hid set up within the automobile. There are both inner and ItagPro external GPS antennas: in other words, anti-loss gadget external antenna is non-obligatory. The device is embedded with rechargeable backup battery. Three LED indicators help during the set up and diagnostic. Queclink GV300 shouldn't be waterproof. Thanks to GNSS chip from ublox and useful firmware Queclink GV300 helps: multi-system navigation (GPS and GLONASS), Assisted GPS (A-GPS) know-how and Cell ID based location. The overall sensitivity is good enough (if essential you'll be able to connect an external GPS antenna). Along with adjustable tracking modes all of these assure reliable and accurate GPS tracking. There are number of inputs in GV300, together with analog ones, which allow to attach multiple automobile sensors of varied varieties. To regulate external equipment a few outputs is used. One serial interface (sort RS232) lets join, on user’s alternative, digital gas stage sensor, camera, PND (Garmin protocol is supported) or external CAN reader. As a GPS tracker manufacturer Queclink is well known for its useful gadgets with comprehensive firmware, and GV300 will not be the exception. The firmware allows to configure lots of choices (including distant control over GPRS), detect a wide range of events, read information from CAN bus and digital gasoline level sensors, use Garmin-appropriate PND, monitor driving behaviour. The firmware of Queclink GV300 can be up to date OTA (Over-the-Air). There is just one RS232 serial interface, which could be a limitation if you would like to attach multiple digital gadgets, i.e. two gas sensors or gas sensor and camera. For these cases RS485 interface would be higher, but there is no such thing as a such an interface.

The results obtained in laboratory checks, utilizing scintillator bars learn by silicon photomultipliers are reported. The current approach is step one for iTagPro online designing a precision tracking system to be placed inside a free magnetized volume for the charge identification of low energy crossing particles. The devised system is demonstrated in a position to supply a spatial resolution higher than 2 mm. Scintillators, Photon Solid State detector, particle monitoring devices. Among the planned activities was the construction of a gentle spectrometer seated in a 20-30 m3 magnetized air volume, the Air Core Magnet (ACM). The entire design should be optimised for the determination of the momentum and cost of muons within the 0.5 - 5 GeV/c vary (the mis-identification is required to be less than 3% at 0.5 GeV/c). 1.5 mm is required contained in the magnetized air volume. On this paper we report the outcomes obtained with a small array of triangular scintillator ItagPro bars coupled to silicon photomultiplier (SiPM) with wavelength shifter (WLS) fibers.

This bar profile is here demonstrated able to provide the mandatory spatial decision in reconstructing the place of the crossing particle by profiting of the cost-sharing between adjacent bars readout in analog mode. SiPMs are wonderful candidates in replacing normal photomultipliers in lots of experimental circumstances. Tests have been carried out with laser beam pulses and radioactive source with the intention to characterize the scintillator iTagPro official bar response and SiPM behaviour. Here we briefly current the noticed behaviour of the SiPM utilized in our tests concerning the main sources of noise and the impact of temperature on its response and linearity. Several models and packaging have been thought of. The primary supply of noise which limits the SiPM’s single photon resolution is the "dark current" rate. It is originated by cost carriers thermally created in the sensitive volume and present in the conduction band and due to this fact it depends on the temperature. The dependence of the dark present single pixel fee as a function of the temperature has been investigated using Peltier cells so as to change and keep the temperature managed.

Dark current charge relies upon also on the Vwk as proven in Fig. 3. As a way to have low charges of dark present the value of Vbias has been mounted at 1.5 V giving a working voltage Vwk of 29 V. It is evident that, iTagPro official if necessary, it can be convenient to use a bias voltage regulator iTagPro official which robotically compensates for temperature variations. Not at all times the pixels of the SiPM work independently from one another. Photoelectrons (p.e.) can migrate from the hit pixel to another indirectly fired by a photon. Optical cross-speak between pixels leads to a non-Poissonian behaviour of the distribution of fired pixels. An estimate of the optical cross discuss likelihood could be obtained by the ratio double-to-single pulse rate as a perform of the temperature. The likelihood depends weakly on the temperature and the measured stage of cross-talk (15-16%) is suitable with the one reported within the datasheet. SiPM response as soon as its primary parameters and cells configuration are given.
